❄️ Winter Road Salt & Grime
How do I safely remove winter road salt?
Road salt and winter grime build up on paintwork, wheels, wheel arches and underneath vehicles. Regular removal helps reduce corrosion risks.
- Rinse loose salt and grit thoroughly.
- Apply a suitable citrus pre-wash or traffic film remover.
- Allow the recommended dwell time. Never let chemicals dry.
- Rinse thoroughly, especially wheel arches and accessible lower areas.
- Follow with a safe contact wash.
Recommended: Stjärnagloss Först X, Autobrite Citrus Pre Wash and suitable pre-wash cleaners.
SHOP PRE-WASH PRODUCTS →How often should I wash my car in winter?
During heavily salted conditions, aim for weekly cleaning where practical, particularly after driving on treated roads.
Even a careful rinse can help remove loose salt when a full wash is not possible.
Always avoid rubbing salt-covered paintwork before removing grit and dirt.
Does ceramic coating protect against road salt?
A ceramic coating can help protect paintwork and make winter dirt easier to remove.
However, ceramic coatings do not eliminate corrosion risks or protect every exposed metal component.
Regular washing remains essential, including wheels, arches and suitable underbody areas.
🛣️ Tar & Paint Decontamination
What are the black spots on my paintwork?
Small black spots on lower doors, sills and rear panels are often road tar or bitumen.
They can be particularly noticeable on white and light-coloured vehicles.
Use a dedicated automotive tar remover rather than scraping or aggressive rubbing.
SHOP TAR REMOVERS →How do I remove tar without scratching paint?
- Wash and rinse the affected area.
- Check the product's surface compatibility.
- Apply tar remover as directed.
- Allow it to dissolve contamination without drying on the surface.
- Gently remove loosened residue.
- Rinse and wash again if instructed.
GYEON Q²M Tar REDEFINED is one option available from our range.
What is the difference between tar and iron remover?
Tar removers target sticky road tar and bitumen deposits.
Iron removers target ferrous contamination such as embedded brake dust and industrial fallout.
They perform different jobs and should not be treated as interchangeable products.
SHOP IRON REMOVERS →💎 Ceramic Coatings & Water Beading
Why has my ceramic coating stopped beading?
Don't panic! Your ceramic coating may not have failed.
Road salt, traffic film, tar, iron fallout and mineral deposits can mask the coating's water-repellent properties.
Try these steps:
- Thoroughly pre-wash the vehicle.
- Carry out a safe contact wash.
- Use a suitable ceramic maintenance shampoo such as GYEON RestartWash.
- Remove tar or iron contamination where necessary with compatible products.
- Rinse thoroughly and reassess the water behaviour.
If water behaviour returns, contamination was likely masking the surface.
If it does not, the coating may require further inspection or maintenance.
Can I use snow foam on ceramic coatings?
Yes. Use a snow foam suitable for coated vehicles and follow its instructions.
Regular pre-washing helps reduce the amount of dirt remaining before contact washing.
SHOP SNOW FOAM →How long does ceramic coating last?
Durability depends on the coating, surface preparation, application, mileage, storage and maintenance routine.
Always treat the manufacturer's quoted durability as conditional rather than a guarantee for every vehicle.
Regular safe washing and appropriate maintenance help preserve performance.
🚿 Safe Washing & Snow Foam
Is snow foam really necessary?
Snow foam can help soften and loosen dirt before contact washing, reducing the amount of contamination left on paintwork.
It is not a replacement for a proper contact wash, and foam thickness alone does not indicate cleaning strength.
SHOP SNOW FOAM →How do I avoid swirl marks when washing?
- Start with a thorough pre-wash.
- Rinse away loosened contamination.
- Use a clean, quality wash mitt.
- Use plenty of shampoo lubrication.
- Rinse the mitt regularly.
- Dry using a clean, soft drying towel.
Never use a dropped or contaminated wash mitt on your paintwork.
🛞 Wheel & Tyre Care
How often should I clean my wheels?
Weekly or fortnightly cleaning is useful for many vehicles, depending on mileage, brake dust and winter road conditions.
Use a wheel cleaner suitable for the wheel finish and avoid applying products to hot wheels.
SHOP WHEEL CARE →Can wheel cleaner damage alloy wheels?
Some strong cleaners can damage sensitive finishes when used incorrectly.
Always check compatibility, dilution, dwell time and manufacturer instructions, particularly for bare, polished, anodised or damaged wheel finishes.
🌧️ Glass & Wet Weather Driving
What does a windscreen rain repellent do?
A dedicated glass repellent helps water form droplets and run off treated glass.
Performance depends on speed, weather, application and windscreen condition.
Always prepare glass thoroughly and maintain functioning wipers.
